A further object of the invention is to provide a substantial means for supporting the necessary machine mountings or other strucinside or the outside of the panel.

'And a still further objectv of the invention is to provide means which not only actsas a support for machine or structural members but also aids in .stiiinening the panel. Y n

These objects are attained in theV following manneryreicerence being had to the accompanying drawings',V in' which Fig. 1 is a side viewet my. improved panel;

The drawings illustrate panels'particularly usedin connection'with drying'maehinery, in'which' heated air; isjcirculated to drymaterial located Within tleidlel 01""traversing through the drier. The channel shown in Fig. vSis one of the rails on which the car- 'riers travel, While Fig. 7 shows afan bracket,

but4 it will be understood that the invention can be used'for any type vof drier or other machine requiring an insulated casing, and where the inner and outer sheets are not of sufficient strength in themselves to support Y `the machine elements or structural work.

' Referring' to Figs. l, 2 and 3, l is a panel made of two thin sheets of steel or other metal, the outside sheet 2 of the panel having a deep flange?) which is extended as at 4 to rest against thelanges 6 of the 'inner sheet '5. The two surfaces are welded together by spot-'weldingatfm.l 7 are reinforcing angles located 'at the corners of the outer sheet. 49--9 are two channel members vertically arranged in thepresent instance and extending the full height of the panel. .The chan; nel is welded at y to the inner sheet and is spaced from theA outer^ sheet. Any suitable non-conducting Vmaterial is located between the'two sheets of the panel. This non-ccnducting material is preferably corrugated asbestos board, and this asbestos non-conduct- 'ing material extends` between the front. sheet and the `channel member as clearly shown'in Fig. 4, so as to prevent through-metal contact romthe inside of the drier to the outsident this point. i A VIn Vsome instances the channel members may be .welded or-Otherwise' secured4 to the outside sheet and. spaced from the inside sheetf" While I have shown the channels arranged vertically, l they may bearranged Vhorizontally in some instances or at anyV angle,',depending. particularly upon the character. ofthe sheet and arrangement of the panel; l Y y The channel members have a series ofholes V.llypunched ineach liange as shown, and these holes :areof such a distance apart as to permit the mountingof any machine elements onstruetural members at practicallyany place ei-theron the inner side or outer side of the panel. i l I `'lVhen the panel is assembled, the inner and outer sheets arenot punched but aresolid, 4as shown-'in Figs." 41 and 4, and Wheirit is desired to secure a machine elelnent to thev outside of the panel, as in Fig. 7 for instance which illustrates a bearing bracket 12, then the outer sheet is preferably punched and the asbestos or other non-conducting material exposed at this opening is removed so as to allow the machine element to come in contact with the channel member.

In this instance, the hole 13 in the front sheet is circular and the bracket 12 has a corresponding boss 14 which extends into the hole and bears against the flange of the channel member 9. The hole in the channel member is elongated as shown in Fig. 5. A bolt 15, Fig. 9, is used, having an elongated head 16 which can be passed through the opening 11 in the channel member and turned at right angles so that the head will overlap the sides of the opening. This bolt extends through the bracket 12 as shown in Fig. 7, and a nut 17 is applied to the bolt which firmly secures the bracket to the channel member.

If a rail or other structural member 1.8, Fig. 8, is to be secured to the inner side of the panel, then a rectangular hole 19 is cut in the inner sheet 5 in line with one of the openings 1l in the channel member as in Fig. 6 and a bolt 15a of the same general type as the bolt shown in Fig. 9 is inserted in the elongated rectangular opening, while a nut 17a is applied which secures the structural member 18 rigidly to the channel member. In this instance the structural member rests directly against the inner sheet which is in contact with the inner flange of the channel.

By the foregoing description of this invention it will be noticed that the number of panels necessary to be carried in stock is greatly reduced, as panels having special punchings .to suit different types of driers need not be provided, as the panels can be punched if necessary after being set up, so as to allow the machine elements or structural work to be firmly secured either to the outside of the panel or to the inner side thereof.

The perforations in the channels can be located so `close together that they permit the 'mounting of any machinery kor structural member at any place desired. The channel members also naturally strengthen the panel., and the inner and outer sheets may consequently be `made of lighter material than heretofore, where the machine elements or structural members were secured directly to the sheets of the panel.

l/Vhile I have shown a particular form 0f panel vin which the outer sheet is flanged and securely welded to the inner sheet, the invention can be applied to other forms of panels without departing from the essential features of the invention; and while I vhave used .the term panel, it is to be strictly understood that it is to cover any structural wall `using spaced inner and .outer sheets, between which is provided an air space or a space for nonconducting material.

Furthermore, while I have shown both flanges of the channel members perforated so that the machine elements or structural Work can be attached vto either side of the panel, in some instances, where the machine elements or structural work is secured to one side only, then the flange of the channel at that side may be perforated only, while. the other side may be solid.

I claim 1. The combination of inner and outer plates spaced apart; and a channel member located between the plates, the channel member Vhaving a series of perforations in line with one of said plates, so that the plate can be punctured at one of the perforations to allow a bolt or other fastening to be attached to the channel member by which a machine element or structural member can be secured to the channel.

2. The combination of inner and outer sheets spaced apart with channel members located between the plates, the channel members being perforated at intervals so that when the structure is assembled the inner or outer sheets can be perforated at a point in line with one of the perforations in the channel so that a machine element or structural Ionember can be secured to the channel memers.

3. The combination in a panel, of inner and outer sheets spaced apart and secured at their edges; and channel members within the panel and located between the inner and outer sheets, the flanges of said members lying parallel with the sheets and having perforations therein so that either sheet can be perforated in line with one of the perforations in one of the channel members for the reception of securing means for machine elements or structural members.

4. The combination in a panel, of two inner and outer sheets spaced apart and secured together at their edges; and a channel member within the panel and located between the inner and outer sheets, the flange of the channel member being in contact with and secured to one of said sheets andspaced from the other sheet, said channel member being perforated at intervals so that one of the sheets may be perforated in line with the perforations in the channel, to allow for the attachment of securing means for machine elements or other structures.

5. The combination in a panel,of inner and outer sheets spaced apart and connected at their edges; non-conducting material located between the sheets; and a channel member located within the panel between the sheets, the flange of the channel member being perforated at intervals so that the sheets can be punctured to allow fastening means gtoy engage the channel member.

6. The combination in a panel, of two sheets spaced apart; non-conducting material in the space between the sheets; and channel members located between the sheets, the flange of one member being secured directly to one of said sheets and spaced from the other sheet, the non-conducting material extending between the sheet and the channel, said channels being perforated at intervals so that a sheet can be perforated in line with the perforations in the channel, to allow for the attachment of securing means directly to the channels.

7. The combination in a panel, of two inner and outer sheets; a channel member located in the space between the sheets and secured to one of said sheets and spaced from the other sheet; non-conducting material in the space between the two sheets and extending between the channel and one of said sheets, said channel member beingperforated at intervals, the sheet which is spaced from the channel member having a perforation greater in size than the perforation in the channel; a machine element having a boss extending through the perforation in the sheet and bearing direct-ly against the channel member; and a bolt for attaching the machine element directly to the channel member.

8. The combination in a panel, of two inner and outer sheets spaced apart, the sheets being connected at their edges; two vertically arranged channel members extending from one end of the sheet to the other, said channel member being secured directly to the inner sheet and spaced from theouter sheet; and non-conducting material in the space between the sheets, said material extending between the channel and the outer sheet, the flanges ofthe channels being perforated at close intervals so that either sheet can be perforated in line with any one of the perforations, to allow for the attachment to thel panel of machine elements or structural work.

9. The combination in a panel, of inner and outer sheets spaced apart; and a perforated member located between the two sheets and arranged so that when one of said sheets is perforated a machine element can be attached to said perforated member through the perforations in the sheet.

10. The combination in a panel, of inner and outer plates spaced apart; and an angular member located between the plates, said member having a series of perforations near one of the plates. so that said plate can bel punched at one of the perforations to allow a fastening means of a machine element or structural member to be attached to the said angular member through the plate.
